Wiper blade for a car

ABSTRACT

A wiper blade for a car comprises a seat part, a moisture absorptive part, and a sweep part. The seat part is an elongated strip made of non-absorptive material and provides a cross section and a length thereof corresponding to a wiper frame on the car for joining with the wiper frame. The moisture absorptive part is made of water absorbable material and has a length and a width thereof corresponding to the seat part for joining with the seat part. The sweep part is an elongated strip with a gap and has a size corresponding to the absorptive part for joining with the absorptive part. The moisture absorptive part can keep the sprayed water for next wipe as soon as the sweep part removes the foreign substances on a windshield of the car.

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a wiper blade for a car, andparticularly to an improvement of wiper blade used on a car.

[0003] 2. Description of Related Art

[0004] It has been a long period of time for a car being a tool of rideinstead of walk or a tool of transportation. Undoubtedly, the car givesour daily lives and industrial and commercial activities muchconveniences and it makes the distance between us short substantially.

[0005] The windshield wiper is one of essential accessories on a car andit performs a function of cleaning the windshield. Especially, the dirtand dust may attach to the windshield while the car is driven duringraining to influence the visual line. The mosquito and moth are frequentto impact the windshield so as to stain thereon while the car is drivenat night or to pass by a wild area such as agricultural zone, or forestzone so that it is hard to remove them. In addition, droppings of wildbirds also constitute stains on the windshield. For experienced drivers,it is believed that they have been affected by the preceding drawbacks.Hence, the windshield wiper becomes an important apparatus for cleaningthe foreign substances staining on the windshield.

[0006] The conventional wiper provides an elongated wiper frame or a setof wiper frames and a sweep part, i.e., the wiper blade is mounted onthe wiper frame with a scratching strip. The wiper blade and thescratching strip are made of EPDM and scratching strip assists thewiping movement so as to remove the water residue completely Thus, assoon as the driver actuates the spraying device over the windshield, thesweep part is used for cleaning the windshield and then the scratchingstrip at a lateral side of the wiper frame or provided independently canmake a sweep afterward to remove the water residue stayed on thewindshield.

[0007] Although the preceding way to clean the windshield can performthe function of eliminating the water thereon basically, there is adefect that the EPDM is unable to absorb the water. Hence, part of watersprayed on the windshield can be cleaned and the rest of water isremoved by way of the scratching strip. It can be realized that thesprayed water is only utilized once and it is a kind of waste for thelimited sprayed water, and it is unfavorable for a long way drive for acar. Especially, the sprayed water is mixed with expensive cleaningagent and the loss of sprayed water means wasting the precious resource.In addition, it is necessary to clean the windshield once more and morein order to clean the pollute strongly stained on the windshield.

SUMMARY OF THE INVENTION

[0008] An object of present invention is to provide a wiper blade for acar, which is possible to absorb the sprayed water for further wipes soas to save the limited sprayed water prepared in the car.

BRIEF DESCRIPTION OF THE DRAWINGS

[0009] The present invention can be more fully understood by referringto the following description and accompanying drawings, in which:

[0010]FIG. 1 is a sectional view of wiper blade being attached to awindshield wiper without a scratching strip according to the presentinvention;

[0011]FIG. 2 is a sectional view of wiper blade being attached to awindshield wiper with a scratching strip according to the presentinvention in a embodiment thereof; and

[0012]FIG. 3 is a fragmentary perspective view of wiper with wiper bladethereon according to the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Referring to FIGS. 1, 2, and 3, an improvement of wiper bladeaccording to the present invention basically resides in that the wiperblade can absorb the sprayed water for further use of next wipe orsubsequent wipes so that the wiper of present invention comprises a seatpart 1, a moisture absorption part, and a wipe part 3.

[0014] Wherein, the seat part 1 is made of hard and non-absorptivematerial such as EPDM. The seat part 1 is an elongated strip andprovides a cross section thereof corresponding to a wiper frame so as tobe inserted into or joined to the wiper frame for engagement. FIG. 3shows the wiper blade is inserted into the engaging groove B in thewiper frame A with a conventional way. It is noted that the arrangementin FIG. 3 is an example only and the way of attaching the wiper blade tothe wiper frame A completely depends on the shape of seat part 1 on awiper blade.

[0015] The moisture absorptive part 2 is made of water absorbablematerial such as a sponge and provides a function of keeping somesprayed water such that the sprayed water can release from theabsorptive part 2 during next wipe. The absorptive part 2 has a widthand a length corresponding to the preceding seat part and can be fixedlyattached to the seat part by way of joining of adhesive or the like.

[0016] The sweep part 3 is used for contacting with windshield andperforming sweep job such that it is made of fiber such as a scratchingcloth, which provides clearances between fibers and is frequently usedas cleaning cloth, or the like. A facial end of sweep part 3 contactswith windshield and has a flat end surface or an arc end surface. Incase of an arc end surface, a central gap may be left between the sweeppart 3 and the moisture absorptive part 2.

[0017] Referring to FIG. 3 again, the wiper blade at the seat part 1thereof is fixedly attached to the wiper frame such that the sweep part3 contacts with the windshield while in use. Once the clean job starts,the water is sprayed over the windshield first and then the wiper bladesweeps the windshield. In this way, the foreign substances on thewindshield can be removed and the sprayed water can be absorbed by andkept in the absorptive part 2 for next or further wipes. That is, thewater kept in the absorptive part 2 can release to wet the windshield toassist the sweeping operation of sweep part 3.

[0018]FIG. 2 shows a scratch part combines with the wiper blade. Ascratch strip 4 extends upward in a slant direction and is made of thesame material as the seat part 1 without the property of waterabsorption.

[0019] It is appreciated that the present invention allows part of thesprayed water being recycled for further use while the windshield iswiped. The function of further use of sprayed water leads to a wellutilization of sprayed water effectively and to prolong the sprayedwater prepared in a car or to increase the frequency of use for thewater. This is a feature not possible for the conventional wiper toreach feasibly.

[0020] While the invention has been described with reference topreferred embodiments thereof, it is to be understood that modificationsor variations may be easily made without departing from the spirit ofthis invention, which is defined by the appended claims.
